Description

Technical Field

[0001] This invention relates to a terminal block, and more particularly to a modular and easily assembled power-feed terminal block. Background Technology

[0002] With the vigorous development of science and technology industries, terminal blocks are widely used in various fields such as automation control, communication equipment, and power equipment. This allows assembly personnel to quickly perform wiring for connecting multiple sets of power lines, control lines, and data transmission lines. It also enables frequent changes in the types of products being produced, allowing for flexible scheduling and combination of automated or manual production to achieve efficient production of small batches and multiple specifications.

[0003] However, terminal blocks generally come in various specifications, so manufacturers need to produce and stock large quantities of terminal blocks with different numbers of wire holes, which puts pressure on manufacturing and warehousing costs. In addition, with the market demand for high efficiency and high performance in recent years, the more wire holes a terminal block has, the more complex its internal structure becomes and the more difficult it is to assemble.

[0004] In view of this, the inventor has devoted himself to research and applied theoretical principles to address the shortcomings of the prior art, and has made every effort to solve the above-mentioned problems, which is the target of the inventor's improvement. Summary of the Invention

[0005] The main objective of this invention is to enable the terminal block to be modularized and easy to assemble, while also facilitating the expansion or reduction of the number of wires required for connection.

[0006] To achieve the above objectives, the present invention provides a power-feed terminal block for connecting multiple wires. It includes an insulating shell, a power supply conductive plate, and at least one wiring module. The insulating shell has a cavity and at least two wire insertion holes communicating with the cavity. The power supply conductive plate is disposed within the cavity. The wiring module is mounted on the power supply conductive plate and includes a power-feed conductive plate, at least two insulating supports, and at least two clamping springs. The power-feed conductive plate is electrically connected to the power supply conductive plate and has a first sidewall and a second sidewall facing each other. Each insulating support is arranged side-by-side on the power-feed conductive plate. Each insulating support, together with the second sidewall, forms a clamping space corresponding to each wire insertion hole. Each clamping spring is fitted onto each insulating support, and one end of each clamping spring elastically abuts against the first sidewall. The other end of each clamping spring is located within each clamping space and can operably clamp or release each wire.

[0007] In another embodiment of the present invention, each insulating bracket includes a transverse side plate and a longitudinal side plate, and the transverse side plate, the longitudinal side plate and the second side wall together enclose the clamping space.

[0008] In another embodiment of the present invention, each clamping spring includes an abutting section, a locking section, and a sleeve section connecting the abutting section and the locking section. Each transverse side plate extends with a support shaft, and the sleeve section sleeves the support shaft, so that the abutting section elastically abuts against the first side wall and the locking section elastically locks against the second side wall.

[0009] In another embodiment of the present invention, the second sidewall is provided with a number of barbs facing the first sidewall corresponding to each of the insulating supports, and each barb engages with the engaging segment to axially restrict each of the clamping springs.

[0010] As another embodiment of the invention, it also includes several release sliders, each of which is slidably disposed on one side of each wire socket and presses against each snap-fit ​​segment to control the communication between each wire socket and each clamping space.

[0011] In another embodiment of the present invention, the first sidewall and the second sidewall are provided with a plurality of grooves corresponding to each insulating bracket, and each longitudinal side plate is provided with a plurality of inserts corresponding to each groove of the first sidewall and the second sidewall, and each insert is respectively embedded in each groove of the first sidewall and the second sidewall.

[0012] In another embodiment of the present invention, a locking block is protruding in each of the grooves of the first sidewall and the second sidewall, and each locking block of the first sidewall and the corresponding insert interfere with each other to lock and secure.

[0013] In another embodiment of the present invention, each of the transverse side plates is provided with a connecting post and a connecting hole on both sides, and the connecting post of each transverse side plate is fixed in the connecting hole of the adjacent transverse side plate.

[0014] In another embodiment of the present invention, each of the insulating supports is integrally formed.

[0015] In another embodiment of the present invention, the power supply end conductive plate is provided with several riveting posts, and the feed end conductive plate of the wiring module is provided with several riveting holes, each of the riveting holes is fitted with the respective riveting post and riveted to fix it.

[0016] This invention also has the following advantages: By fitting each rivet post into each rivet hole and riveting it in place, the power supply conductive plate can be fixed to the power supply conductive plate to form an electrical connection. Through the grooves in the first and second side walls, the inserts of each longitudinal side plate can be fitted in, thus fixing each insulating bracket to the power supply conductive plate. Through the locking blocks inside each groove, interference locking with each insert can further enhance the locking effect. Through the connecting posts and connecting holes on the left and right sides of the transverse side plates, each insulating bracket can be connected in series with each other. Through the several barbs on the second side wall, each locking segment can be engaged with each other to axially restrict each locking segment. Through the release sliders provided on one side of each wire insertion hole, each locking segment can be pressed to control the communication between each wire insertion hole and each clamping space.

Detailed Implementation

[0026] The detailed description and technical content of the present invention will be explained in conjunction with the accompanying drawings. However, the accompanying drawings are for illustrative purposes only and are not intended to limit the present invention.

[0027] This invention provides a power-fed terminal block for connecting multiple wires A. Please refer to... Figures 1 to 7 As shown, the power-fed terminal block mainly includes an insulating shell 10, a power supply conductive plate 20, and at least one wiring module 30.

[0028] The insulating shell 10 is integrally molded from plastic injection molding, but the present invention is not limited thereto; for example, the insulating shell 10 can also be made of other insulating materials. The insulating shell 10 has a cavity 11, and the insulating shell 10 is provided with at least two wire insertion holes 12 and a power supply wire insertion hole 13 communicating with the cavity 11. Each of the wires A is inserted into the cavity 11 through the respective wire insertion hole 12. In this embodiment, the wiring structure of the power supply wire insertion hole 13 is bolt-type, that is, a power supply wire B is fastened to a conductive box 40 by a bolt C to achieve electrical connection, but the present invention is not limited thereto; for example, the wiring structure of the power supply wire insertion hole 13 can also be spring-loaded.

[0029] In this embodiment, the power supply conductive plate 20 is a long strip of metal plate with good conductivity (such as silver, copper, gold, aluminum, steel, or any of the aforementioned alloys), but the present invention is not limited thereto; any plate with good conductivity is acceptable. The power supply conductive plate 20 is disposed within the cavity 11. Specifically, the power supply conductive plate 20 is disposed at the bottom of the cavity 11 and contacts the conductive box 40 inside the power supply wire socket 13 to form an electrical connection, thereby enabling the power supply wire B and the power supply conductive plate 20 to be electrically connected.

[0030] Please see Figures 3 to 5 As shown, the wiring module 30 is mounted on the power supply conductive plate 20, and mainly includes a power supply conductive plate 31, at least two insulating supports 32, and at least two clamping springs 33. In this embodiment, the number of wiring modules 30 is four and arranged longitudinally along the power supply conductive plate 20. However, the present invention is not limited to this. For example, the number of wiring modules 30 can also be two, three, or more than five. The designer can adjust the number of wiring modules 30 according to different needs. In this embodiment, the number of insulating supports 32 and clamping springs 33 in each wiring module 30 is three. However, the present invention is not limited to this. For example, the number of insulating supports 32 and clamping springs 33 in each wiring module 30 can also be two or four or more, or the number of insulating supports 32 and clamping springs 33 in different wiring modules 30 can be different, depending on the designer's needs. It is worth noting that the power supply conductive plate 31, each insulating bracket 32, and each clamping spring 33 of the wiring module 30 in each figure are only schematic for ease of understanding, and therefore the size and quantity of each component should not be regarded as a limitation of the present invention.

[0031] The feed-end conductive plate 31 is a metal plate with good conductivity (such as silver, copper, gold, aluminum, steel, or any alloy thereof), but the present invention is not limited thereto; any plate with good conductivity is acceptable. The feed-end conductive plate 31 is stacked on the power supply conductive plate 20 to form an electrical connection with the power supply conductive plate 20, and has a first sidewall 311 and a second sidewall 312 facing each other. In this embodiment, the power supply conductive plate 20 is provided with a plurality of riveting posts 21, and the feed-end conductive plate 31 is provided with a plurality of riveting holes 313 corresponding to each riveting post 21. Each riveting hole 313 is fitted with a riveting post 21 and then riveted to fix the feed-end conductive plate 31 onto the power supply conductive plate 20 to form an electrical connection. However, the present invention is not limited thereto; any material that can effectively fix the two and form an electrical connection is acceptable.

[0032] The insulating bracket 32 ​​is integrally molded from plastic injection molding, but the present invention is not limited thereto; for example, each insulating bracket 32 ​​can also be made of other insulating materials. Each insulating bracket 32 ​​is arranged side by side on the feed end conductive plate 31, and each insulating bracket 32, together with the second side wall 312, forms a clamping space 321 corresponding to each wire socket 12. Specifically, the insulating bracket 32 ​​is generally L-shaped and includes a transverse side plate 322 and a longitudinal side plate 323, and the transverse side plate 322, the longitudinal side plate 323, and the second side wall 312 together enclose the aforementioned clamping space 321. In this embodiment, several slots 311A ​​and 312A are respectively provided on the first sidewall 311 and the second sidewall 312 corresponding to each insulating bracket 32. Each longitudinal side plate 323 has a corresponding insert block 322A and 323A on its front and rear sides, respectively. Each insert block 322A and 323A is embedded in the corresponding slot 311A ​​and 312A, thereby fixing each insulating bracket 32 ​​to the feed end conductive plate 31. Preferably, at least one locking block 311B and 312B can also be protruded from the inner side of each slot 311A ​​and 312A. The interference locking between the locking blocks 311B and 312B and the insert blocks 322A and 323A can further enhance the locking effect between each insulating bracket 32 ​​and the feed end conductive plate 31.

[0033] Please see Figure 8 As shown, each transverse side plate 322 has at least one connecting post 322B and at least one connecting hole 322C on its left and right sides respectively. The connecting post 322B of each transverse side plate 322 is fixed in the connecting hole 322C of the adjacent transverse side plate 322, thereby enabling the insulating supports 32 to be connected in series. One of the outer insulating supports 32 is symmetrically formed to form an insulating support 32'. The insulating support 32' extends symmetrically to the left and right sides with two transverse side plates 322, two support shafts 322D and two connecting holes 322C, thereby enabling the installation of two clamping springs 33. However, the present invention is not limited to this. For example, each insulating support 32 can also be a single piece integrally formed by plastic injection molding.

[0034] The clamping spring 33 is a metal spring with good conductivity, but the present invention is not limited thereto. The clamping spring 33 includes an abutting section 331, a snap-fit ​​section 332, and a sleeve section 333 connecting the abutting section 331 and the snap-fit ​​section 332. Each clamping spring 33 is respectively sleeved on each insulating bracket 32, and one end of each clamping spring 33 elastically abuts against the first sidewall 311, while the other end of each clamping spring 33 is located in each clamping space 321 and can operably clamp or release each of the said wires A. Specifically, each transverse side plate 322 extends laterally with a support shaft 322D. A sleeve section 333, in an arc shape, is sleeved on the support shaft 322D, allowing the end of the abutment section 331 to elastically abut against the first side wall 311, while simultaneously allowing the end of the snap-fit ​​section 332 to elastically snap against the second side wall 312, thus fixing each clamping spring 33 to the power supply end conductive plate 31. Preferably, the second side wall 312 has several barbs 312C facing the first side wall 311 corresponding to each insulating bracket 32. Each barb 312C snaps against each snap-fit ​​section 332 of each clamping spring 33, axially restricting each snap-fit ​​section 332, so that after snapping, each snap-fit ​​section 332 can only swing downwards to facilitate the insertion and clamping of the wire A.

[0035] For further explanation, please refer to the following: Figure 1 , Figure 2 , Figure 6 and Figure 7 The power-fed terminal block also includes several release sliders 50 corresponding to the number of wire sockets 12. Each release slider 50 is axially slidably disposed on one side of the corresponding wire socket 12 and penetrates into the cavity 11 to contact the clamping springs 33 and press against the locking sections 332, thereby controlling the communication between the wire sockets 12 and the clamping spaces 321. Specifically, when each release slider 50 is pressed downward along the axial direction, it presses down the locking sections 332 of the corresponding clamping springs 33, thereby establishing communication between the wire sockets 12 and the clamping spaces 321, facilitating the insertion or removal of the wires A; when each release slider 50 is released, each clamping spring 33 can use its own elasticity to re-lock the locking sections 332 against the barbs 312C, and push the release slider 50 back to its position. The insulating housing 10 also includes a side cover 14. The side cover 14 is installed on one side of the insulating housing 10, thereby covering and shielding the power supply conductive plate 20 and each wiring module 30.

[0036] Of course, the present invention may have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can devise various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the protection scope of the patent application of the present invention.
